Assembled flame-retardant heat-insulation wall body unit for cold storage warehouse and production method thereof

Abstract

The invention discloses an assembled flame-retardant heat-insulation wall body unit for a cold storage warehouse. The assembled flame-retardant heat-insulation wall body unit for the cold storage warehouse comprises a core layer, a surface layer and support frames, wherein the surface layer covers four side surfaces of the square core layer; the two support frames are respectively embedded into the surface layer from the upper and lower bottom surfaces of the core layer and are fixed with the surface layer; the core layer is formed by inorganic fiber filling materials and inorganic fiber spray coating bonding agents through matched synchronous spray coating filling; the surface layer is jointly defined by a wall face plate and a semi-enclosure metal frame; the metal frame comprises a metal face plate, a first connecting plate and a second connecting plate; the first connecting plate and the second connecting plate are respectively arranged at the two ends of the metal face plate; and the metal frame is used for the splicing joint of adjacent wall body units for the cold storage warehouse. The invention also discloses a production method of the wall body unit. The production method has the major steps of splicing a box-shaped structure; fixing a mold; performing spray coating filling; and forming shaping and mould removal. The invention relates to the field of building, and provides the assembled flame-retardant heat-insulation wall body unit for the cold storage warehouse and a mould pressing spray coating filling production method thereof. The assembled flame-retardant heat-insulation wall body unit for the cold storage warehouse has the advantages of high integral intensity, high heat insulation performance and obviously enhanced flame-retardant performance.

Description

technical field [0001] The invention relates to the field of construction, in particular to an assembled flame-retardant and thermal insulation cold storage wall unit and a production method thereof. Background technique [0002] Cold storage is an essential building for heat preservation and storage of fresh goods. It requires basic properties such as heat preservation and sealing. The traditional technology is often made of organic insulation materials such as polyurethane, expanded polystyrene, and expanded phenolic formaldehyde, and laminated metal plates on both sides. The disadvantage is that it uses a large amount of adhesives, but it is difficult to ensure uniform bonding. The foam layer is peeled off from the surface layer due to the excessive thermal expansion and contraction caused by the change of hot and cold temperatures, which leads to the deterioration of the strength, heat preservation and airtight performance of the wallboard.
